{"cve":"CVE-2026-26316","nvd":{"published":"2026-02-19T22:16:47.110","modified":"2026-06-17T10:26:04.757","status":"Analyzed","description":"OpenClaw is a personal AI assistant. Prior to 2026.2.13, the optional BlueBubbles iMessage channel plugin could accept webhook requests as authenticated based only on the TCP peer address being loopback (`127.0.0.1`, `::1`, `::ffff:127.0.0.1`) even when the configured webhook secret was missing or incorrect. This does not affect the default iMessage integration unless BlueBubbles is installed and enabled. Version 2026.2.13 contains a patch. Other mitigations include setting a non-empty BlueBubbles webhook password and avoiding deployments where a public-facing reverse proxy forwards to a loopback-bound Gateway without strong upstream authentication.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5},"cwes":["CWE-863"],"references":["https://github.com/openclaw/openclaw/commit/743f4b28495cdeb0d5bf76f6ebf4af01f6a02e5a","https://github.com/openclaw/openclaw/commit/f836c385ffc746cb954e8ee409f99d079bfdcd2f","https://github.com/openclaw/openclaw/releases/tag/v2026.2.13","https://github.com/openclaw/openclaw/security/advisories/GHSA-pchc-86f6-8758"],"products":["openclaw:openclaw"],"source":"nvd","synced_at":"2026-10-19T22:23:35.260773158+00:00"},"epss":{"cve":"CVE-2026-26316","score":0.00363,"percentile":0.30182,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-pchc-86f6-8758","url":"https://osv.dev/vulnerability/GHSA-pchc-86f6-8758","summary":"OpenClaw BlueBubbles webhook auth bypass via loopback proxy trust","modified":"2026-02-20T16:58:43.992121Z","packages":[{"ecosystem":"npm","name":"openclaw","purl":"pkg:npm/openclaw","ranges":["<2026.2.13"],"fixed":["2026.2.13"]},{"ecosystem":"npm","name":"@openclaw/bluebubbles","purl":"pkg:npm/%40openclaw/bluebubbles","ranges":["<2026.2.13"],"fixed":["2026.2.13"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
